Vessel, remove the end plug and inspect the Brine O-Rings for wear or damage. Replace them if wear
or damage is present.
b. Solution: Replace the O-Ring if wear or damage is present.
Automated Motor-Actuated Back Pressure Regulator
Prior to assuming that the Back Pressure Regulator’s Electric Motor Actuator has failed, perform a Function Test.
1. Problem: The Operating Pressure is higher than normal when the System is operated in the Automatic
mode.
a. Description: When the System Feed Water is higher than normal in salinity and/or lower than normal in
temperature, the operating pressure will automatically increase in an attempt to produce the specified amount
of Product Water. Pressure will increase until the Product Water flow is achieved or until the operating
pressure reaches 950 PSI (66 BAR).
b. Solution: The System is programmed to not exceed 950 PSI (66 BAR) operating pressure. No correction is
necessary.
2. Problem: The Operating Pressure is lower than normal when the System is operated in the Automatic
mode.
a. Description: The Product Water Flow reading at the Touch Pad indicates that the System is producing the
specified amount of Product Water. However, the Operating Pressure is lower than normal. When the System
Feed Water is lower than normal in salinity and/or higher than normal in temperature the operating pressure
will automatically decrease to not exceed the specified amount of product water. Pressure will decrease
until the specified product water flow is achieved.
b. Solution: The System is programmed to not exceed the specified amount of Product Water Flow. No correction
is necessary.
3. Problem: The Operating Pressure does not increase when the System is operated or does not decrease
when the System is stopped when operated in the Automatic Mode.
a. Description: The Back Pressure Regulator Valve is controlled by a gear motor arrangement. The Valve is
coupled to the gear shaft with a female coupler. The set screws holding the gear shaft or Valve shaft to the
coupler may have become loose. The gear shaft is turning but the valve shaft is not. When the System Feed
Water is lower than normal in salinity and/or higher than normal in temperature the operating pressure will
automatically decrease to not exceed the specified amount of product water. Pressure will decrease until
the specified product water flow is achieved.
b. Solution: Tighten the set screws to secure the gear shaft and valve shaft to the coupler if they are loose.
4. Problem: The gear shaft does not rotate at all.
a. Description: The Electric Motor and or gear assembly may not be functioning.
b. Solution: Repair or replace the Back Pressure Regulator.
Brine Discharge Flow Meter
Prior to assuming that the Brine Discharge Water Flow Meter has failed, check the Control Logic model setup.
1. Problem: The Brine Flow Meter does not register the proper Brine Water Flow at the Touch Pad.
a. Descriptions:
a. Debris may be trapped within the flow meter body, causing false readings.
b. There may be a water substantial leak prior to the Brine Flow Meter, resulting in a lower than normal
reading.
